Sebastian Falbesoner 7720d4f650 test: fix failure in feature_nulldummy.py on single-core machines ...

On single-core machines, executing the test feature_nulldummy.py results in
the following assertion error:

...
2021-08-18T15:37:58.805000Z TestFramework (INFO): Test 4: Non-NULLDUMMY base multisig transaction is invalid after activation

The behaviour can be reproduced on a multi-core machine by simply changing the
function GetNumCores() (in src/util/system.cpp) to return 1:

int GetNumCores()
{
    return 1;
}
